[0002] With the advancement of technology and the enhancement of environmental awareness, in recent years, aerated concrete bricks (referred to as blocks) have gradually replaced traditional red bricks or blue bricks and become the preferred material in many large-scale civil engineering projects. After the blocks are cut into pieces, they form a pile of blocks. The pile of blocks needs to be sent to the bundling station and the blocks are bundled by the bundling machine, such as Figure 5 As shown in the figure. The blocks are stacked on a pallet. When they are tied, the forklift lifts the pallet carrying the blocks (the pallet has space for the forklift's fork to enter) and moves the blocks to the truck. Obviously, this method of transporting blocks must rely on a pallet, and each time a block is transported, a pallet is needed, which will waste a lot of pallets and add extra costs to the manufacturer.

[0016] As Figure 1 shown, this multi-station trayless packing production line comprises a rotary spreader 1, a first conveying device 2 and a block gripping device 4. The rotary spreader 1 can lift the whole or part of the block stack and rotate it, and at the same time can move the blocks to various positions. The rotary spreader 1 is a prior art; the first conveying device 2 can convey the blocks forward, which is a prior art; the block gripping device 4 can grip the blocks and move them to a certain position, which is also a prior art.

[0017] In order to form two fork holes 10 in the block stack, as Figure 5As shown, firstly, the conventional stacking mode (A) of the block pile is transformed into a stacking mode (B) in which one layer is arranged vertically by means of the rotating sling 1. The specific transformation process is as follows: the rotating sling 1 lifts the blocks except the lowest layer and then rotates, so that the blocks are arranged vertically and placed on the blocks of the lowest layer. Then, the rotating sling 1 lifts the blocks except the blocks of the lowest two layers and then rotates, so that the blocks are arranged horizontally and placed on the blocks of the second layer. Thus, the following is formed: Figure 5 Secondly, in order to be able to take out two rows of blocks on the second layer of blocks and form two fork holes 10, a clamping and lifting device 3 is provided on one side of the block clamping device 4; Figure 2 As shown, the clamping and lifting device 3 includes a lifting frame 30 and two left and right clamping and lifting mechanisms. The first conveying device 2 passes through the bottom of the lifting frame 30. After the first conveying device 2 conveys the block stack to the bottom of the lifting frame 30, as shown in FIG. Figure 5 As shown, two clamping and lifting mechanisms lift the upper part of the block pile, making it easier for the block clamping device 4 behind to extract two rows of blocks. Figure 2 As shown, the clamping and lifting mechanism includes a clamping plate 31, a clamping power source 33, a lifting seat 32 and a first lifting power source 34. The clamping plate 31 is connected to the clamping power source 33 in a transmission manner. The clamping power source 33 is installed on the lifting seat 32. The lifting seat 32 can slide up and down on the lifting frame 30. The first lifting power source 34 is connected to the lifting seat 32 in a transmission manner. The two clamping plates 31 of the left and right clamping and lifting mechanisms are arranged opposite to each other.

[0018] The working principle of the clamping and lifting device 3 is as follows: after the first conveying device 2 conveys the block pile to the bottom of the lifting frame 30, the clamping power source 33 drives the clamping plate 31 to move forward (the clamping power source 33 is a cylinder), so that the left and right clamping plates 31 clamp the upper part of the block pile, and then the first lifting power source 34 drives the lifting seat 32 to move upward, so that the left and right clamping plates 31 clamp the upper part of the block pile and move upward (such as Figure 5 At C in the figure), the subsequent block clamping device 4 can enter to clamp two rows of blocks to form two fork holes.

[0019] like Figure 1 The block clamping device 4 is used to enter the lifting frame 30 to clamp two rows of blocks, as shown in FIG. Figure 3As shown in the figure, the block clamping device 4 includes a clamping frame 40, a lifting frame 42, a second lifting power source, a translation seat 44, a translation power source 45, and two grippers 41 for clamping blocks. Each gripper 41 clamps a row of blocks. The two grippers 41 are installed on the lifting frame 42. The lifting frame 42 is arranged on the translation seat 44 in a liftable manner. The second lifting power source can drive the lifting frame 42 to lift and lower on the translation seat 44. The translation seat 44 is arranged on the clamping frame 40 in a horizontally slidable manner. The translation power source 45 can drive the translation seat 44 to move on the clamping frame 40. The two grippers 41 can enter the lifting frame 30.

[0020] The working principle of the block clamping device 4 is as follows: When the clamping and lifting device 3 lifts the upper part of the block stack upward, the translation power source 45 drives the translation seat 44 to move forward, so that the two grippers 41 enter the lifting frame 30. Then the second lifting power source drives the lifting frame 42 to lower, so that the two grippers 41 come above the lower part of the blocks. Then the two grippers 41 respectively clamp two rows of blocks, and through the movement of the translation seat 44, these two rows of blocks are transported to other places, so that fork holes 10 can be formed in the block stack (such as at D in Figure 5 ). After that, the clamping and lifting device 3 lowers the upper part of the block stack (such as at E in Figure 5 ), thus completing all the work of forming fork holes in the block stack. After that, it can enter the subsequent packing station (such as at F in Figure 5 ), and is packed by the bundling machine 6 (the bundling machine 6 is a prior art). Finally, the two fork angles of the forklift can be inserted into the two fork holes 10 to transport the blocks away.

[0021] The block clamping device 4 can clamp out two rows of blocks and place them aside. However, this method will cause waste of these blocks. In order to arrange these blocks, these blocks can be re-entered onto the first conveying device 2 to complete the same packing work as above. As shown in Figure 1 , the present invention also provides a second conveying device 5 below the clamping frame 40. The second conveying device 5 is located on one side of the first conveying device 2. The block clamping device 4 clamps two rows of blocks and places them on the second conveying device 5 each time. After multiple clamps and placements, a block stack as shown at A in Figure 5 is formed. Then the rotary sling 1 transfers the block stack on the second conveying device 5 to the first conveying device 2, and thus circulates and enters the above process.

[0022] As shown in Figure 3As shown, the clamping hand 41 of the block clamping device 4 includes a clamping arm 410, a front clamping plate 412 and a rear clamping plate 413. The front clamping plate 412 and the rear clamping plate 413 are both installed on the clamping arm 410 (the front clamping plate 412 is hinged at the front end of the clamping arm 410, and the rear clamping plate 413 is fixedly installed). The front clamping plate 412 is driven to rotate by the first clamping power source 414 (the first clamping power source 414 is a cylinder), and the front clamping plate 412 and the rear clamping plate 413 can realize the clamping action.

[0023] In order to facilitate the building block clamping device 4 to clamp two rows of building blocks and place them into a pile, the two clamping hands 41 of the building block clamping device 4 can be relatively slidably arranged on the lifting frame 42, and the lifting frame 42 is equipped with a separation power source 43 that drives the two clamping hands 41 to move relative to each other. Driven by the separation power source 43, the two clamping hands 41 can move relative to each other and move closer, so that the building block clamping device 4 can bring the two rows of building blocks together, and after multiple stacking, a stacked building block is formed. Figure 5 The pile of blocks at A in the middle.

[0024] In order to drive the two grippers 41 to slide relative to each other, Figure 4 As shown, a guide rail 420 is installed on the lifting frame 42, and two grippers 41 are slidably arranged on the guide rail 420. A first rack 46 is installed on one gripper 41, and a second rack 47 is installed on the other gripper 41. The tooth surfaces of the first rack 46 and the second rack 47 are arranged opposite to each other. A gear 48 is arranged between the first rack 46 and the second rack 47. The gear 48 is meshed with the first rack 46 and the second rack 47 respectively, and the separation power source 43 is connected to the gear 48. When working, the separation power source 43 drives the gear 48 to rotate, and the gear 4 drives the first rack 46 and the second rack 47 to move in opposite directions, so that the two grippers 41 can be relatively close or relatively far away.

[0025] Finally, it is worth mentioning that the second conveying device 5 includes a conveying rail 50 and a conveying trolley 51, and the conveying trolley 51 can move forward and backward on the conveying rail 50. After the block clamping device 4 clamps two rows of blocks, they are prevented from being put on the conveying trolley 51. When the block pile is formed, the conveying trolley 51 carries the block pile to one side of the rotating hanger 1, and the rotating hanger 1 lifts it and sends it to the first conveying device 2.
